Method of making laminated glass

Abstract

A method and apparatus for the laminating of glass is described. Glass sheets are transported by a gantry which places the sheet on a workstation. The glass sheet is allowed to dish and a second sheet is placed over the first sheet after depositing a resin on the first sheet. The trolley and the workstation from a press to complete the lamination process.

I claim: 
     
       1. A method of laminating flat sheets of glass comprising the steps of forming a concavity in a central zone of a first sheet by applying force to the sheet, depositing a predetermined quantity of a settable composition in the concavity, locating a second sheet over the first sheet, applying a sealant which is liquid impermeable and air permeable on the first or second sheet prior to or after locating the second sheet on the first sheet, causing the first and second sheets to assume a planar position and applying sufficient pressure on the sheets for the resin and air to flow outwardly in the interspace between the sheets. 
     
     
       2. A method of laminating glass according to claim 1 including the step of laying the first and second sheets in a planar position in a vacuum chamber, and at least partially evacuating the chamber while allowing the resin to flow in the interspace between the sheets. 
     
     
       3. A method according to claim 1 wherein the sealant comprises a liquid impermeable and gas permeable tape applied on either the first or the second sheets, said method including the step of applying pressure in a central zone of the second sheet located over the first sheet to cause the second sheet to contact the resin. 
     
     
       4. A method according to claim 1 which includes the step of forming a meniscus with the composition as the second glass sheet is located over the first glass sheet and allowed to contact the composition.
